Abstract
An energy damping device that includes a piston-cylinder assembly (12) having a cylinder and a piston (22) movable therein. A pre-loaded double acting spring (12), and a friction assembly (14), are enclosed fully within the cylinder, and engage the piston concentrically. The spring acts against the friction assembly for forcing it into frictional engagement with the inner surface of the cylinder.
The friction assembly includes at least one wedge (25) for engaging the interior surface of the cylinder. The friction assembly further includes a plurality of spaced-apart compression rings (30,33,36), that are interleaved with the wedges, for forcing them into radially outwardly directed frictional engagement with the interior surface of the cylinder.
